Last modified

CVE-2021-43620 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. An issue was discovered in the fruity crate through 0.2.0 for Rust. Security-relevant validation of filename extensions is plausibly affected. EPSS estimates a 1.31% chance of exploitation in the next 30 days.

Description

An issue was discovered in the fruity crate through 0.2.0 for Rust. Security-relevant validation of filename extensions is plausibly affected. Methods of NSString for conversion to a string may return a partial result. Because they call CStr::from_ptr on a pointer to the string buffer, the string is terminated at the first '\0' byte, which might not be the end of the string.
